The robotic manipulator

This present study proposes a design and the analysis of the novel adaptive robust neural networks (ARNNs) based on the backstepping control method for industrial robot manipulators (IRMs). In this research, the ARNNs controller has combined the advantages of Radial Basis Function neural network (RBFNN), the robust term, and adaptive backstepping control technique without the requirement of prior knowledge.

The primary function of these robots is to move to the site and manipulate elements which present risk, while well as transmit images with cameras. Behind all the mechanical engineering that supports the structure and gives the robot the ability to interact with its surroundings, a sophisticated electronic system that operates the different robot systems (caterpillars, cameras, manipulator arm) is hidden.

The paper presents a complete generalized procedure based on the Euler-Lagrange equations to build the matrix form of dynamic equations, called dynamic model, for robot manipulators. In addition, a new formulation of the Coriolis/centrifugal matrix is proposed. The link linear and angular velocities are formulated explicitly. Therefore, the translational and rotational Jacobian matrices can be derived straightforward from definition, which make the calculation of the generalized inertia matrix more convenient.

This article presents analysis of inverse dynamics of a serial manipulator in milling process. With the exception of positioning accuracy issue, machining by robots have more advantages than by conventional CNC milling machines, due to higher flexible kinematics (many links and degrees of freedom) and larger working space. Therefore, motion of the robot links is more complicated. Process forces and complicated motion involve to difficulties in solving dynamic problems of robots. This affects the robot control to match machining requirements.

Computing the optimal geometric structure of manipulators is one of the most intricate problems in contemporary robot kinematics. Robotic manipulators are designed and built to perform certain predetermined tasks. There is a very close relationship between the structure of the manipulator and its kinematic performance. It is therefore important to incorporate such task requirements during the design and synthesis of the robotic manipulators.

A computational algorithm is developed for estimating accurately the attitude of a robotic arm which moves along a predetermined path. This algorithm requires preliminary input data obtained in the static mode to yield phase observables for the precise, 3-axis attitude determination of a swinging manipulator in the dynamic mode. Measurements are recorded simultaneously by three GPS L1 receivers and then processed in several steps to accomplish this task.
